Blockade of the BAFF trimer–trimer interaction by belimumab. Partially transparent surface model of two neighboring BAFF trimers (purple and white) and a ribbon representation of one BAFF trimer (red, orange, and yellow for each protomer) in complex with belimumab Fab (heavy chain: blue; light chain: green). The dotted ellipse indicates a steric collision between the adjacent BAFF trimer and the bound belimumab
